Jawaban:

Dengan menerapkan konsep komposisi fungsi.

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell left parenthesis straight g ring operator straight h right parenthesis left parenthesis straight x right parenthesis end cell equals cell straight g left parenthesis straight h left parenthesis straight x right parenthesis right parenthesis end cell row blank equals cell 2 left parenthesis straight h left parenthesis straight x right parenthesis right parenthesis minus 3 end cell row blank equals cell 2 left parenthesis 2 minus straight x right parenthesis minus 3 end cell row blank equals cell 4 minus 2 straight x minus 3 end cell row blank equals cell negative 2 straight x plus 1 end cell end table end style 

Jadi, begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell left parenthesis straight g ring operator straight h right parenthesis left parenthesis straight x right parenthesis end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank minus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 2 end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank straight x end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank plus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 1 end table end style   

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell left parenthesis straight f ring operator left parenthesis straight g ring operator straight h right parenthesis right parenthesis left parenthesis straight x right parenthesis end cell equals cell straight f left parenthesis straight g ring operator straight h right parenthesis left parenthesis straight x right parenthesis right parenthesis end cell row blank equals cell left square bracket left parenthesis straight g ring operator straight h right parenthesis left parenthesis straight x right parenthesis right square bracket squared minus 2 left square bracket straight g ring operator straight h right parenthesis left parenthesis straight x right parenthesis right square bracket minus 3 end cell row blank equals cell left parenthesis negative 2 straight x plus 1 right parenthesis squared minus 2 left parenthesis negative 2 straight x plus 1 right parenthesis minus 3 end cell row blank equals cell 4 straight x squared minus 4 straight x plus 1 plus 4 straight x minus 2 minus 2 end cell row blank equals cell 4 straight x squared minus 3 end cell end table end style
